This paper concerns the application of the predictive direct torque control (PDTC) method to a permanent magnet synchronous generator (PMSG). In classical methods for controlling a PMSG, the sampling frequency of the controller must be precisely determined. However, the use of PDTC in this study enables three optimal duty cycles to be predicted at the moment of sampling, significantly reducing the ripple of the electromagnetic torque and the amplitude of the stator flux below those caused by conventional control methods. Therefore, the new method allows a lower sampling frequency than the traditional method. To operate the machine side converter, the DC bus capacitor voltage must be maintained within an acceptable and stable range. Voltage-oriented vector control is used to control the active power and the reactive power, which are delivered from the DC bus capacitor, as well as to control the voltage. In this study, a complete wind turbine system is considered, including a focus on the aerodynamics and structure of each wind turbine, using Fatigue, Aerodynamics, Structures and Turbulence (FAST). Also, to prevent the rotor speed of the wind turbine from exceeding the rated rotor speed too much, a very simple pitch controller system is considered. V C 2015 AIP Publishing LLC. [http://dx.

“…Betz theory states that the theoretical maximum value of p C is around 0.59, yet a real wind turbine cannot reach it, usually 0.48 [3]. A wind turbine needs to keep p C at maximum so as to produce maximum power, which requires the turbine to maintain an optical tip speed ratio opt .…”

The paper introduces a full-open experimental platform for doubly-fed induction generator (DFIG), which based on wind energy conversation system. The paper starts from the working principles of doubly-fed induction generator (DFIG), then the controlling strategies of girdconnection and variable-speed-constant-frequency (VSCF) and maximum-power-point-tracking. The effects of the controlling strategies were examined in Matlab/Simulink environment. Finally, a full-open experimental platform was developed based on TMS320F28335 and PLC. Controlling strategies of DFIG were applied on the platform by DSP programming. The experiments results verified the validity and efficiency of the controlling strategies, and showed the stability of the platform.

This paper investigates the performance of a fault-tolerant four-switch three-phase (FSTP) grid-side converter (GSC) in a doubly-fed induction generator-based wind turbine (DFIG-WT). The space vector pulse width modulation (SVPWM) technique is simplified and unified duty ratios are used for controlling the FSTP GSC. Steady DC-bus voltage, sinusoidal three-phase grid currents and unity power factor are obtained. In addition, the balance of capacitor voltages is accomplished based on the analysis of current flows at the midpoint of DC bus in different operational modes. Besides, external disturbances such as fluctuating wind speed and grid voltage sag are considered to test its fault-tolerant ability. Furthermore, the effects of fluctuating wind speed on the performance of DFIG-WT system are explained according to an approximate expression of the turbine torque. The performance of the proposed FSTP GSC is simulated in Matlab/Simulink 2016a based on a detailed 1.5 MW DFIG-WT Simulink model. Experiments are carried out on a 2 kW platform by using a discrete signal processor (DSP) TMS320F28335 controller to validate the reliability of DFIG-WT for the cases with step change of the stator active power and grid voltage sag, respectively.
